It's supposed to work. Is there any error output from 'make'?

Sorry, iu have been out of the loop for a while, but i tried to
install comedi modules from the source (git) and there is nothing
inside lib/modules/2.6.37/comedi

i have disabled all comedi refs in the kernel conf file, so there is
nothing at staging/comedi

but also, make install does not produce any comedi modules, just an
empty lib/modules/2.6.37/comedi directory.

Am I missing something? Many thanks!

Hey Ian,

the only thing I can see is this:

Hi Ian,

that's my whole make output. It appears to me that it runs rather fast
and the modules do not seem to be compiled (do I have to write
anything special in the configure:

It looks like there's a bug in the comedi/include/asm/uaccess.h file as
it doesn't include <linux/version.h> before using the LINUX_VERSION_CODE
and KERNEL_VERSION macros.

The simplest option is to remove the file, as it's only a kernel
compatibility header for really ancient kernels that we don't support
any more! Alternatively, you could add the following line just before
the bit that checks LINUX_VERSION_CODE:

#include <linux/version.h>

The thing that's confusing me now is why it builds fine on my system!

[Narigas]

awesome! the drivers are there! thanks heaps!
